There is a difference between the gas connection diameter and the diameter of the supply line. Always use the most adequate diameter of the supply
line to minimize the pressure drop through the gas pipes. If necessary, reduce the diameter of the supply line at the inlet of the unit

.
Minimum height from floor to bottom surface of heater for safe use of heater. Positioning of unit heaters for proper performance is application
dependent. Operation is affected by other air moving equipment in the space, obstructions to the airflow, draughts and/or close proximity to doors
or windows, etc. Care should be taken to avoid mounting the heaters higher than these recommendations, unless downturn nozzle options are used,
as significant stratification may occur resulting in poor floor coverage and higher energy losses through the roof structure. Isothermal cond/-
20°C ambient air temperature, discharge louvres zero deflection, v = 0.5m/s. The air throw will be influenced by the height of the building, mounting
height of the unit, ambient temperature & adjustment of the louvres.
